Create CoreEngineConfig

Method Detail

getDatasetClass

public java.lang.Class<? extends RDFDataset<?>> getDatasetClass()

Specified by:

getDatasetClass in interface EngineConfig

Returns:

The RDFDataset subclass to use for identifying and retrieving data graphs to query against.

getTreeRewriters

public java.lang.Iterable<TreeRewriter> getTreeRewriters()

Specified by:

getTreeRewriters in interface EngineConfig

Overrides:

getTreeRewriters in class DefaultEngineConfig

Returns:

An enumeration of TreeRewriters that will be applied sequentially to transform the SPARQL query tree before query execution.

getQueryValidators

public java.lang.Iterable<QueryValidator> getQueryValidators()

Specified by:

getQueryValidators in interface EngineConfig

Returns:

An enumeration of QueryValidators that will be invoked sequentially to determine if the engine will execute the given query.

getQueryExecutionPlan

public java.lang.Class<? extends QueryExecutionPlan> getQueryExecutionPlan()

Specified by:

getQueryExecutionPlan in interface EngineConfig

Returns:

The QueryExecutionPlan class to use for putting together a plan of access for executing the query.

registerFunctionalPredicate

public void registerFunctionalPredicate(java.lang.String predicate,
                                        java.lang.Class<? extends FunctionalPredicate> clazz)

Register FunctionalPredicate with this engine config

Parameters:

predicate - to register

clazz - to instantiate

getFunctionalPredicates

public java.util.Map<java.net.URI,java.lang.Class<? extends FunctionalPredicate>> getFunctionalPredicates()

Specified by:

getFunctionalPredicates in interface EngineConfig

Returns:

A map associating predicate URIs with FunctionalPredicates that implement special semantics for that URI.

includeInferredTriples

public boolean includeInferredTriples()

Should query results include inferred triples Note:Not yet implemented

Specified by:

includeInferredTriples in interface EngineConfig

Returns:

the includeInferredTriples

setIncludeInferredTriples

public void setIncludeInferredTriples(boolean includeInferredTriples)

Set if query results should include inferred triples Note:Not yet implemented

Parameters:

includeInferredTriples - the includeInferredTriples to set
